Well, the AS5 has had time to settle and still no joy. At load I'm seeing 22C water yielding 43-44C die temperature, which is still in the same range as the other three blocks. I'm starting to suspect that using an ambient system, it's going to be hard to break through that 22C differential barrier. I'm burned out on this block. About the only thing left to try, at a lot of effort, is to pull the NB and GPU blocks out of the loop, running the 1250 to the CPU block only. My gut feeling is that this is not a flow issue. I sincerely feel that I'm down to the source impedance of the high power-density core and the series resistance of the TIM being the limiting factors. I can't stress enough that "this is not your fathers Tbred" we're talking about.
